To all whom t may concern:

` Be it known that I, ELIAS B. REQUA, of

ot" New Jersey, have invented certain new and useful Improvements in Lanterns, ot' wliiclrthe following is a specitication. Iv l Thisinvention relates to the class oflanterns adapted for burning light hydrocarbons.`

Its object isto supply the burner and globe with an abundance of air for the support of the iiame and for carrying ott' the products ot combustion, to increase-fthe illuminating 'power of the lantern by causing `the ame to extend `higher into `the globe than heretofore, and to prevent Bic-kering `of the liiame. y 'l llt consists mainly, first, in` 'a 'lantern hav? ing thelower end of its globe closed by an in'- wardly'- extending deilector providedv with a anie-slot-,said deflectorresting upon an annular foraniinous corrugated-band or wallv which surrounds the burner, whereby a reservoir of -air is formed around-the burner, and the inward tlow ot' airy thereto, whileampleiu quantity-and evenly distributed, has its current-forcechecked5 second, in a lanternwhaving the lower end of itsglobe closed by an inwardly extending deflector provided with a flame-slot, said detlectorresting upon an annular foraminous corrugated band or wall en -V circling the'top of the oil-fount andsurrounding the burner, the said fount being provided with air-passages leading from its bottom to within said foraminous band or wall, and said fount being further provided with foramino'us screens or walls arranged between the lower ends of its air-passages and the outer air.`

By this arrangement a supplyof air is guar!V anteed from the bottom of the lantern, and also laterally above the oillfount, and the two'ilows are caused to impinge upon each other and neutralize each others force. The screens and foraminous walls subdivide the' flow of air, check its force, and cause an even distribution of air around the iiame.

In the accompanying drawings, Figure l is a view, in elevation, of a lantern embracing my improvement. .Fig 2 is a vertical diametric section of same. Fig. 3 is a top perspective view of the base with the globe and its combined holder and deiector removed. Fig.

The letterAindicatesthe oil-toont. supplied with a burner, B,of any suitable construction, having an air-chamber surrounding its wicktuber lUpon the top of the oil-fountY is arranged aforaminousV corrugated band, C, en-

\ circlingthe burner, and having a diameter about equalfto the `base of Va combined "globeholder and deiiector, D, which rests upon it. This globe-holder `and defieetor is approxi: mately cone-'shaped,iiaringsomewhatabruptly 1 at its base, and lhaving a'tlange, b, extending upward from its edge,and` provided with a lip,- c, which"` is the portion of. the detlector which bearsimmediately uponfftbe b'and C.

' Within the ila-nge b iits the base of the globe E," and the'tlaring `portion ot the cone is provided with rows ot perforations.

Vertical] y through the oil-fount arearran ged air-passages f,and the said fount is provided ao'cess ot" air tothe lower ends ot' said passages. Below the bottom ot' the oil-fount is hinged a false, bottom,-h, having a vcentral aperture, y aroundltheledge of whichis arrau ged a forami- .with a t'oraminousbase-rim, g,permitting'free 1 nous wall, ,'from which radiate four perforated Y walls, la, so that when the false bottom is closed the space between thebot'tom is divided into four chambers, into' each of which opens one ofthe air-passages f, passing through the fount.

VThe letter L designates the lantern-cap, consisting of anfnpwardly-tapering band,m, t-

` ting upon the top of the globe and surrounded by another band, n', the lower edge of which rests upon the wall ot' the inner band and has 'recesses o in it, forming air-passages. The inner band, m, has around its base a row of perforations, r, which admit air' to its interior to reenforce the upward draft and cause a rapid exit of the products of combustionfrom the globe. The outer band extends somewhat above the other, and has "upward projecting `arms p,

which support a dished disk, q, which is thev cover of the cap. The cap is hinged in the ordinary manner tolone of thev globe-guards, Vand is secured to the other byja springcatch.

The operation of the lantern kis as follows: When the wiel; in the burner is lighted air flows through the perforated wall of the base of the fount and through the aperture of the IOO false bottom and the foraminous walls to the air-passages f, through which it flows to the space inclosed by the serpentine or corrugated band C, surrounding the base of the burner, and thence, through the foraminons wall of the base-chamber of the burner, it ows to the base of the iiame. A large amount of air is thus supplied to the flame and its initial currentforce considerably checked; but it is still liable to assume the form of separate upward currents, which it is desirable to disperse and mingle to form a general store of air, giving an` evenly-distributed supply all around the base of the iiame. This object is accomplished by the laterally-inward flow of the air through the perforations of the serpentine or corrugated band C, which is given its peculiar form in order that it may intercept currents ot' air lowing in any direction andhave a large surface and a great number of fine perforations to permit the passage of a great amount of air evenly distributed, the iiow of which impinges against the air iiowing up through the passa ges f, breaks its force, and causes it to spread under the deflector D, so that the iiamedraws its supply from a still reservoir of ample capacity. A portion of the air from the reservoir iiows through the perforations in the flaring portion of the deflector D, and creates an upward current through the globe, which carries upward the products of combustion. This current is reenforced by the air iowin g into the cap L through the perforations r, so that the products 0f combustion are caused to pass rapidly from the globe Without leaving any deposit thereon, and the air owing through the apertureso upward between the inner and outer bands of the cap, and then escaping under the edges of the cover q, forms at the top of the cap outward lateral currents, which prevent any portion of thel products of combustion from being reflected back into the globe.

It will be observed that, as the deflector D directs a very large supply of air upon the llame and through its flame-slot, the iiame will be caused to extend high up into the globe, and thus the radiation of light will be but little intercepted by the base portions of the lantern.

Having fully described my invention, what I claim is- 1. A lantern having the lower end of its globe closed by an inwardly-extending deflector provided with a flame-slot, said dedector resting upon an annular foraminous corrugated band which surrounds the burner, substantially as and for the purpose set forth.

2. A lantern having the lower end of its globe closed by an inwardly-extending deflector provided with a dame-slot, said deflector resting upon an annular foraminous corrugated band or wall encircling the top'of the oil-fount and surrounding the burner, the sald fount being provided with air-passages leadingfron] its bottom `to within said foraminous bandor wall, and said fount being further provided with foraminous screens or walls arranged between the lower ends of its air-passages and the outer air, substantially as and for the purpose set forth.

3. The combination of the oil-fount having the air-passages therethrough, the kfalse lbottorn provided with the perforated walls and central aperture, the foraminous corrugated wall surrounding the top of the oil-fount and burner, and the deilector resting upon said wall,

substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand and sealin the presence of the subscribing witnesses.
